“
I orederd a pair of JH 16Pro IEMs in May. It is now June 15th. Since ordering the first pair, I have returned at my cost of $21.15 each time, the IEMs three times. Each time, Caleb Ellis, who manages the department that makes the IEMs, said he could not explain what had happened.
The left IEM of the first pair fitted perfectly with the impressions I paid an ...” --rollinoswald

The JH13 Pro was my first purchase of high-end personal audio equipment so it's difficult for me to provide a fair comparison (prior to purchasing them, I was listening to iPhone earbuds), but I can safely say that I couldn't possibly be happier with my purchase.
The process of getting the impressions made was painless (albeit a bit expensive in the San Francisco Bay Area), and...” --WKHarmon

“Here's my video review of the universal Roxanne, kindly loaned to me by Jerry Harvey.
Notes: The tips I was using were given to me and are called SpinFit. I don't know of anyone selling them at present, but Jerry Harvey has said he is going to look into making them available.

“Introduction
I decided to buy the CIEM JH5 when I talked to my friend who has the CIEM JH5, JH13 and JH10x3 and he told me that he most CIEM hear is JH5 because it does not show either the "defects" of the music of poor quality or unrecorded and hence to casually listen for hours. How would I already spend good money and did not want to disappoint me made ​​the choice so that my...” --Vitor Valeri

I feel obligated to share out-of-the-gate that I am no CIEM expert! As a matter of fact, I don't even particularly enjoy IEMs - I love over-ear or on-ear headphones. That said: Experiencing JH Audio's JH-13 Pro (now Freqphase) IEMs at Canjam 2009 was nothing short of a revelation for me. As a matter of fact, the experience was so far from anything I had to compare it with that I ended...” --mikemercer

“Looking at the picture of the PK3's I wasn't expecting much. They look and feel cheap using a generic case for the drivers making them easy to fake. (In fact my first pair were fake!) these earbuds sound GREAT! Especially considering the price ($44) I have a few pair of earbuds in this same and higher price range and these PK3's knock all of them out of the water. They have a flat sounding...” --thebluebulk

“I have a Samsung Galaxy Note GT-N7000 (original Note) and most aftermarket earphones have iPhone controls or none. So after reading about different compatible products I decided to try Samsung's dual driver IEMs as much for the best possible inline smartphone controls as for the audio quality. It goes without saying that the inline controls are well designed, easy to use and the mic is of...” --julian67

Got these at Amazon after a long search and much reading. Sound for the price is really good. Not in the same league with my Sony Pros or the Sennheisers but surprisingly close. I have them connected with a REALLY cheap headphone amp and the combo far exceeds what I expected. Clear, roomy, dead quiet.

These were my sweetest sounding head-gear yet. It would be brilliant all-rounder if it would not require a portable amp for portable use. This is the first reason i left it, otherwise i almost got an ear infection from those foams.., they get dirty in a few weeks of massive use. I recommend them to clean, i boiled them in water.
